Abstract The Red Sea (RS) has a high evaporation rate, exceeding 2 m of water per year. vapor is transported from the shorelines by sea breezes as far 200 km landward. Relative humidity in vicinity RS exceeds 80% summer. Nevertheless, precipitation scarce most Arabian coastal plain. In this work we use Weather Research and Forecasting (WRF) regional model to assess how deliberate changes (geoen...

The five elements of the moored array were set in a 50-km 2 pattern centered at 15°30'N, 61°30'E. The central mooring was the most heavily instrumented. Two meteoro­...

The western Arabian Sea exhibits strong spatial variability in sea surface temperature (SST) during the southwest monsoon, with changes in SST that can exceed 58C over 200 km. Exploration of satellite-based and in situ data shows a strong connection between mesoscale SST features and changes in the atmospheric boundary layer. The fundamental relationship is that of weak (strong) wind velocities...

[1] We use measurements of ocean surface dissolved Al, a global Biogeochemical Elemental Cycling (BEC) ocean model, and the global Dust Entrainment and Deposition (DEAD) model to constrain dust deposition to the oceans. Our Al database contains all available measurements with best coverage in the Atlantic. Vertical profiles and seasonal data exist in limited regions. Observations show that surf...

The role of surface forcing in the semiannual evolution of the upper-ocean temperature, salinity, and velocity fields in the Arabian Sea is examined. To do so, variability in the upper ocean in the central Arabian Sea was observed from an array of moorings deployed from October 1994 to October 1995. The Northeast (NE) Monsoon was characterized by moderate winds, clear skies, and dry air; sea-su...

My long-term goal is to contribute to our understanding of the way different marine ecosystems function, and to the role of natural selection and micro-evolutionary processes in ecosystem resistance and resilience. In particular, I am interested in the interaction between physical, chemical, and bio-optical properties of the water column and the distribution, productivity, and genetic diversity...

Identification by Bhattacharya et al. (1994) of seafloor spreading type magnetic anomalies in the basin lying between Laxmi Ridge in the Arabian Sea and the Indian continent necessitates a change in plate tectonic reconstruction. Naini and Talwani (1982) named this basin the Eastern Basin and we will continue to use this term in this paper. Others, in the literature, have called this the Laxmi ...
